Bacteriocytes or mycetocytes together form bacteriomes or mycetomes, which are specialized organs in some insects that house the symbionts. Blastulae Hollow spheres of cells surrounding a cavity of fluid, comprising the early stages in the development of embryos. Ovipositor The tube-like organ ...
The SARS-CoV-2-ACE2 interaction links viral pathogenesis to the function of the renin-angiotensin system (RAS). In the brain, there are a circulating RAS and a local one. The former exerts its effect in circumventricular organs that lack the blood–brain barrier (BBB) and project to nuclei...
Anox is expressed in chemosensory organs and neurons of the central nervous system and appears essential for the regulation of insulin signaling by modulating sugar-induced nerve responses. In this respect, it should be mentioned that lipid and glucose-sensitive neurons of the CNS appear to form ...
This study evaluates Aβ levels in brain, peripheral organs and tissues, suggesting that brain as well as plasma Aβ levels are the consequence of intricate relationships between central and peripehral sources. Article CAS PubMed PubMed Central Google Scholar Li, Q. X., Fuller, S. J., ...
Estrogens: sex hormones, such as estradiol, are secreted in greater amounts by females than by males and contribute to female sex characteristics. Testosterone: in males, stimulates the growth of the male sex organs in the fetus and the development of the male sex characteristics during puberty....
This is a deterioration process that leads to the decay of tissues and organs, and that, in the case of annual, biennial and/or monocarpic plants, leads to the death of the plant itself. The main function of leaf senescence is nutrient recycle and, since this confers an adaptive advantage...
The vagus nerve is the body’s longest nerve, relaying messages between the intestines and the brain while touching many organs in between. It is thought to be a major way that psychobiotics exert influence on the brain. Dr. Ted Dinan’sresearch supports this. ...
are mobile cells. Secondarylymphoid organsand accumulations have T-dependent areas and B-dependent areas. It is much more common to findinnervation, whether noradrenergic or peptidergic, associated with the T-dependent areas. However, occasional fibers do seem to enter the follicles. There are also...
Our findings add a new actor to the complex mechanisms underlying reproductive organ differentiation in flowering plants and provide leads towards addressing the diversity of factors controlling the transition to reproductive organs.This is a preview of subscription content, access via your institution ...
Identification of enteramine, the specific hormone of the enterochromaffin cell system, as 5-hydroxytryptamine. Nature 169, 800–801 (1952). This paper is the first to recognize that enteramine and 5-HT are the same chemical. Article CAS PubMed Google Scholar Twarog, B. M. & Page, I. ...
